Product updates, technical notes and the thinking behind what we build.
The exact solar-position equations, decomposition logic, and Perez coefficient table our engine used to convert GHI/DNI/DHI into plane-of-array irradiance
Every loss stage, every default value, every combination rule — published so a researcher can reproduce our energy cascade from GlobHor down to E_Grid without guessing at a single assumption.
The most common mistake in early-stage design comparison is assuming bigger is better: more modules, higher DC kWp, higher energy output, done. But a plant that's technically optimum is not the one with the largest array — it's the one that extracts the best performance within its equipment limits.
IST PVSolar Simulator was built the other way around: as one connected platform where the calculation engine, Indian regulatory compliance, and bankability reporting were designed together from the start, not stitched on afterward.
How accurately you capture those losses determines whether a project is bankable, whether an investor's IRR model holds up, and whether an EPC's performance guarantee is one they can actually stand behind.
If you've ever tried to get a solar project financed, you already know the drill: a lender or investor won't move on a P50 energy estimate and a nice PDF proposal.
Having all - physics engine, India compliance, bankability financials, and a genuinely multi-currency/multi-country cost-benchmarking layer, what it argues removes the usual need for a Western simulation tool.
This tool was built to compress that entire process — survey, modeling, and reporting — into a single guided workflow you can run from a phone or laptop, without sacrificing the physics that make a shading analysis trustworthy in the first place.
IST PVSolar Simulator is not as a design calculator but as a solar PV industrial research & development instrument. benchmarked against international standards
